Yet another Raspberry PI alarm system. It monitors an area using a passive infrared sensor and if motion is detected, the camara captures 4 pictures which are then sent to a configurable Telegram group or user. Moreover, the system's main functions are controlled using a Telegram bot.

The main program builds upon Python's asyncIO library and is using aiogram3 to interact with Telegram, picamer2 to control the camera and finally pigpio for interfacing with the GPIO.

• Raspberry PI >4
• Camera Module 3
• Passive infrared motion sensor
• Physical push button
• Leds and corresponding resistors
• Enclosure
• Raspberry PI relays board
• (Optional) Piezo Buzzer

• Get your telegram bot token by talking with @botfather
• Create group, get group ID
• Add your bot to this group
• Clone this repository and install requirements:

  # Install OS requirements
  sudo apt install -y python3-libcamera python3-kms++
  sudo apt install -y python3-prctl libatlas-base-dev ffmpeg libopenjp2-7 python3-pip libcap-dev
  
  # Enable "remote GPIO"
  # raspi-config->Interface Options -> Remote GPIO
  
  # Enable pigpiod service on boot
  sudo systemctl enable pigpiod
  
  # Create a new python virtual env inside the cloned repository
  python3 -m venv --system-site-packages venv
  
  # Activate venv
  source venv/bin/activate
  
  # install requirements
  pip install -r requirements.txt
  
  # Edit .env.dist and copy
  cp .env.dist .env

• Adjust the systemd service file and copy to /usr/lib/systemd/system
• Enable on boot: sudo systemctl enable raspi-alarm.service
